How can we increase efficiency of Carnot?

The efficiency of the carnot engine can be increased by either increasing the sink temperature or by decreasing the reservoir temperature.

What does Carnot efficiency depend on?

The Carnot efficiency depends only on the temperature of the hot source and the cold sink. Where: is the heat supplied to the system from a fuel. is the heat given off by the system to the cold sink known as waste heat.

What happens to Carnot efficiency if the source temperature increases?

If the temperature of the source (TH) is increased then the efficiency of the Carnot engine increases.

In which step does a Carnot engine temperature of gas increase?

Fourth step: In this step, the cylinder is placed on the insulated platform and the confined gas is allowed to compress adiabatically. Due to the work is done on the confined gas the temperature of the gas increases and becomes equal to the temperature of the source.

How can we increase the efficiency of a heat engine?

Therefore, the efficiency of the heat engine can be increased by decreasing the temperature of the cold sink or increasing the temperature of the hot source.

How can you increase the efficiency of a Carnot engine should the temperature of the hot reservoir be raised or lowered how about the cold reservoir?

To increase the efficiency of a Carnot engine, should the temperature of the hot reservoir be raised or lowered? What about the cold reservoir? In order to increase the efficiency, the temperature of the hot reservoir should be raised, and the cold reservoir should be lowered as much as possible.

How the efficiency of heat engine can be increased?

In which case efficiency of Carnot engine will be higher?

Solution : The efficiency is given is `eta = (T_1 – T_2)/(T_1), T_1 gt T_2` Now in the two cases the efficiencies are `eta_h = (T_1 + Delta T – T_2)/(T_1 + Delta T), T_1` encreased `eta_l = (T_1 – T_2 + Delta T)/(T_1), T_2` decreased Thus `eta_h lt n_l`.

What is the efficiency of Carnot engine?

The efficiency of carnot’s engine is 50%.

What factors affect the efficiency of a real heat engine?

These factors are the nonzero reference point, external irreversibilities and internal irreversibilities.

What is Carnot efficiency?

Carnot efficiency is the maximum efficiency that a heat engine may have operating between the two temperatures (Figure 2-7). Figure 2-7. Carnot process efficiency. The Carnot efficiency has little practical value. It is a maximum theoretical efficiency of a hypothetical engine.
